DESCRIPTION OF THE EMBODIMENTS

FIG. 1 is a schematic perspective view of a functional module of an electronic device and an assembly thereof to an adaptor module according to an embodiment of the invention. FIG. 2 is a schematic side view of the adaptor module of the electronic device of FIG. 1 assembled to a lamp holder and the functional module thereof removed from the adapter module. Referring to FIG. 1 and FIG. 2, an electronic device 100 of the present embodiment is adapted to be detachably assembled to a lamp holder 9 (shown in FIG. 2). In general, indoor ceiling generally includes a lamp holder 9 in which a light bulb can be installed, and the lamp holder 9 includes a lamp socket 91, such as an E10, E12, E14, E17, E26, E27, or E40 standard female connector. Of course, the type of the lamp socket 91 is not limited thereto.

In the electronic device 100 of the present embodiment, an existing circuit of the lamp holder 9 is used as a power supply circuit for the electronic device 100, and an additional circuit-building procedure is not needed. Moreover, the electronic device 100 can also be directly fixed on the lamp socket 91 after being screwed in the lamp socket 91, and an additional mounting bracket is not needed. In other words, the electronic device 100 of the present embodiment only needs to be directly installed on the existing lamp holder 9 for operation, and the assembly is very simple. Hereinafter, the electronic device 100 of the present embodiment is described in detail.

FIG. 3 is a schematic perspective view of the functional module of the electronic device of FIG. 1 removed from the adaptor module. Referring to FIG. 1 to FIG. 3, in the present embodiment, the electronic device 100 includes an adaptor module 10. The adaptor module 10 includes a lamp connector 11 corresponding to the lamp socket 91, and can be connected to the lamp socket 91 of the lamp holder 9 as shown in FIG. 2. In the present embodiment, the lamp connector 11 is, for instance, an E10, E12, E14, E17, E26, E27, or E40 standard male connector. Of course, the type of the lamp connector 11 is not limited thereto.

As shown in FIG. 3, in the present embodiment, the adaptor module 10 further includes a first connector 121 electrically connected to the lamp connector 11 and an adaptor circuit board 17 electrically connected to the first connector 121 and the lamp connector 11.

In the present embodiment, the type of the first connector 121 is, for instance, different from the type of the lamp socket 91. In other words, the first connector 121 is not a connector for a regular lamp. In the present embodiment, the first connector 121 includes a plurality of curved or circular conductive pads, but the type of the first connector 121 is not limited thereto. In other embodiments, the first connector 121 can also be, for instance, a USB connector, an HDMI connector, or an e-SATA connector. In the present embodiment, the adaptor module 10 is adapted to be docked to the lamp socket 91 via the lamp connector 11 such that the first connector 121 of the adaptor module 10 is electrically connected to the lamp socket 91. In other words, in the present embodiment, when the adaptor module 10 is assembled to the lamp holder 9, the external interface of the lamp holder 9 is changed from the lamp socket 91 to the first connector 121 of the adaptor module 10. If a module has a connector corresponding to the first connector 12, then the module can be directly connected to the adaptor module 10. Of course, in other embodiments, the type of the first connector 121 can also be the same as the type of the lamp socket 91.

In the present embodiment, the adaptor module 10 further includes a first engaging member 13 adjacent to the first connector 121, the adaptor module 10 has a groove 15, the first connector 121 is located in the groove 15, and the first engaging member 13 includes at least one engaging groove 131 adjacent to the outer edge of the groove 15 and connected to the groove 15, but the type of the first engaging member 13 is not limited thereto. In the present embodiment, the number of the engaging groove 131 is, for instance, two, but the number of the engaging groove 131 is not limited thereto.

Moreover, in the present embodiment, the electronic device 100 can further optionally include a functional module 20. In the present embodiment, the functional module 20 includes at least one of a light source module, a camera module, a projection module, a speaker module, a radio module, and a wireless communication module. Of course, the functional module 20 can also be other functional modules, and the type of the functional module 20 is not limited thereto. The functional module 20 includes a second connector 211 and at least one second engaging member 22. The second engaging member 22 of the functional module 20 is detachably connected to the first engaging member 13 of the adaptor module 10. In the present embodiment, the number of the second engaging member 22 is two, and the second engaging member 22 includes an engaging block, but the number and type of the second engaging member 22 are not limited thereto.

It can be seen from FIG. 3 that, the functional module 20 can include a protruding portion 24 corresponding to the groove 15, the second connector 211 is exposed to the protruding portion 24, and the second engaging members 22 are protruded beyond the edge of the protruding portion 24. In the present embodiment, the second connector 211 includes a plurality of pogo pins, but the type of the second connector 211 is not limited thereto as long as the second connector 211 can be docked to the first connector 121.

In the present embodiment, the groove 15 of the adaptor module 10 and the protruding portion 24 of the functional module 20 allow rapid alignment of a user. When the functional module 20 is to be assembled to the adaptor module 10, the second engaging members 22 can be slid into the first engaging member 13 along an inclined plane 132 of the engaging groove 131 simply by aligning the protruding portion 24 of the functional module 20 with the groove 15 of the adaptor module 10 and aligning the second engaging members 22 (such as engaging blocks) with an opening 133 of the engaging groove 131. Since a space 225 (shown in FIG. 2) exists between the second engaging members 22 radially protruding beyond the protruding portion 24 and the housing of the functional module 20, upon completion of the assembly, a portion of the housing of the adaptor module 10 is extended into the space 225 between the second engaging members 22 and the housing of the functional module 20 to complete the engagement. On the other hand, when the functional module 20 is to be detached from the adaptor module 10, the user only needs to rotate the adaptor module 10 to move the second engaging members 22 out of the first engaging member 13 to release the engagement of the first engaging member 13 and the second engaging members 22, and therefore installation and removal are very convenient.

Moreover, it can be seen from FIG. 3 that, the position of the first connector 121 of the adaptor module 10 corresponds to the position of the second connector 211 of the functional module 20, and therefore when the functional module 20 is assembled to the adaptor module 10, the second connector 211 can be in contact with the first connector 121 to be electrically connected to the first connector 121. Therefore, in the present embodiment, when the functional module 20 is assembled to the adaptor module 10 and the electronic device 100 is assembled to the lamp holder 9, the second connector 211 of the functional module 20 is electrically connected to the lamp socket 91 of the lamp holder 9 via the first connector 121 of the adaptor module 10 and the lamp connector 11. In other words, the lamp socket 91 of the lamp holder 9 can provide power to the adaptor module 10 and the functional module 20 for operation, and an additional wiring procedure is not needed.

Moreover, it can be seen from FIG. 3 that, in the present embodiment, the adaptor module 10 can further include at least one first magnetic member 14 adjacent to the first engaging member 13, and in the present embodiment, the adaptor module 10 has two first magnetic members 14, but the number of the first magnetic member 14 is not limited thereto. The first magnetic members 14 can be located in the groove 15, and the connecting line of the two first magnetic members 14 can pass through the center of the groove 15. Moreover, in the present embodiment, the functional module 20 can further include at least one second magnetic member 23 adapted to be attracted to the first magnetic members 14. In the present embodiment, the functional module 20 has two second magnetic members 23, but the number of the second magnetic member 23 is not limited thereto. The second magnetic members 23 are located at the protruding portion 24, and the connecting line of the two second magnetic members 23 can pass through the center of the protruding portion 24. In the present embodiment, the first magnetic members 14 and the second magnetic members 23 are both magnets, and the magnetic pole of the first magnetic members 14 is opposite to the magnetic pole of the second magnetic members 23. Of course, in other embodiments, one of the first magnetic members 14 and the second magnetic members 23 can be a magnet and the other one a magnetic component, and the types of the first magnetic members 14 and the second magnetic members 23 are not limited thereto.

In the present embodiment, when the functional module 20 is about to be installed on the adaptor module 10 and the second engaging members 22 (such as engaging block) is aligned with the opening 133 of the engaging groove 131 (such as the initial position), the first magnetic members 14 of the adaptor module 10 are displaced from the second magnetic members 23 of the functional module 20. At this point, since the second magnetic members 23 of the functional module 20 are attracted by the first magnetic members 14 of the adaptor module 10, the functional module 20 is rotated relative to the adaptor module 10 until the second engaging members 22 slide into the locked position in the first engaging member 13. In other words, in the present embodiment, when the functional module 20 is to be assembled to the adaptor module 10, as long as the protruding portion 24 of the functional module 20 is aligned with the groove 15 of the adaptor module 10, the second magnetic members 23 of the functional module 20 are attracted by the first magnetic members 14 of the adaptor module 10 such that the functional module 20 is rotated to the locked position relative to the adaptor module 10, and installation is more convenient and simpler. Of course, in other embodiments, the electronic device 100 can also omit the first magnetic members 14 and the second magnetic members 23, and the user can also achieve engagement by slightly rotating the functional module 20 in a manual manner. The cooperation of the first engaging member 13 and the second engaging members 22 can provide the effect of rapid installation and removal.

In the electronic device 100 of the present embodiment, via the adaptor module 10 has the design of the lamp connector 11, the adaptor module 10 can be assembled to a regular lamp holder 9, and the adaptor module 10 is assembled to the lamp holder 9 in the same manner that a light bulb is installed, in which the lamp connector 11 of the adaptor module 10 is screwed into the lamp socket 91 of the lamp holder 9 to complete the structural and electrical connection. The user can dispose the electronic device 100 of the invention on a desired lamp holder 9 themselves without requiring an additional procedure to provide a relevant circuit and mounting bracket, and therefore installation and removal are rather convenient.

Moreover, since the functional module 20 can be assembled to the adaptor module 10 in a detachable manner and can be electrically connected to the lamp holder 9 via the adaptor module 10, the user can select the desired type of functional module 20 to be assembled to the adaptor module 10 themselves or switch the functional module 20 as needed to meet the diverse needs of the user. For instance, when the user is to use the projection function, the user only needs to install the functional module 20 having a projection module to the adaptor module 10. When the user is to change to the monitor function, the user can remove the functional module 20 having a projection module and install the functional module 20 having a camera module to the adaptor module 10 instead. Under regular conditions, a functional module 20 having a light source module can also be installed to the adaptor module 10 to provide lighting. Of course, the functional module 20 can also have a plurality of functions at the same time to meet a variety of demands at the same time.

It should be mentioned that, in the present embodiment, the adaptor circuit board 17 of the adaptor module 10 can have, for instance, a voice assistant controller 171, which can provide the function of voice assistant. A signal connection can be established between the adaptor module 10 and the functional module 20 via the first connector 121 and the second connector 211 or via a wireless method. If the functional module 20 having a light source module is installed on the adaptor module 10, then when the voice assistant controller 171 receives an instruction to turn the lights on or off or to adjust the brightness, the functional module 20 can be controlled to operate accordingly using a wired or wireless method to achieve the effect of a smart home. Of course, the voice assistant controller 171 can control different functional modules 20 via settings.

FIG. 4 is a schematic perspective view of a functional module of an electronic device removed from an adaptor module according to another embodiment of the invention. FIG. 5 is a schematic perspective view of the adaptor module of FIG. 4 hiding a cover and the functional module of FIG. 4 hiding a modified cover. FIG. 6 and FIG. 7 are respectively schematic exploded views of the electronic device of FIG. 4 in different perspectives. It should be mentioned that, FIG. 6 and FIG. 7 only schematically show the main elements, and elements such as wires connected between the circuit board and the connectors are omitted. Referring to FIG. 4 to FIG. 7, the main difference between an electronic device 100 a of the present embodiment and the electronic device 100 of the previous embodiment is that the engagement method between an adaptor module 10 a and a functional module 20 a is different from the engagement method between the adaptor module 10 and the functional module 20.

Specifically, as shown in FIG. 5, in the present embodiment, the adaptor module 10 a includes a chute 16 connected to a groove 15 (shown in FIG. 4) and a restoring member adjacent to the bottom of the chute 16. In the present embodiment, the restoring member is exemplified by a first magnetic member 14, but the type of the restoring member is not limited thereto. In the present embodiment, a first engaging member 13 a is movably disposed in the chute 16, the first engaging member 13 a is a latching magnetic component, and the first magnetic member 14 is adapted to be magnetically attracted to the first engaging member 13 a such that the first engaging member 13 a is retracted in the chute 16. In other words, when the adaptor module 10 a is not yet connected to the functional module 20 a, the first engaging member 13 a is attracted by the first magnetic member 14 and retracted in the chute 16.

Moreover, in the present embodiment, a second engaging member 22 a of the functional module 20 a includes an external gear set 222, the external gear set 222 has a plurality of teeth 223, and the adjacent two teeth 223 have an engaging groove 221 therebetween. The functional module 20 a includes a second magnetic member 23 disposed adjacent to the second engaging member 22 a (such as inside). In the present embodiment, the magnetic force of the second magnetic member 23 is greater than the magnetic force of the first magnetic member 14.

Moreover, it can be seen from FIG. 6 and FIG. 7 that, in the present embodiment, the chute 16 of the adaptor module 10 a is formed on both an inner housing 18 and a cover 19, the groove 15 (shown in FIG. 4) is formed on the cover 19, the first connector 12 a is disposed on the cover 19 and located in the groove 15, the adaptor circuit board 17 is located between a housing seat 101 and the inner housing 18, and the inner housing 18 has a hole 181 to allow a wire (not shown) connected between the adaptor circuit board 17 and the first connector 12 a to pass through. A circuit board 26 of the functional module 20 a is located between an outer housing 21 and a separator 27, the second connector 21 a is located on a modified cover 25, and the separator 27 has a perforation 271 and the second magnetic member 23 is a hollow ring to allow a wire (not shown) connected between the circuit board 26 and the second connector 21 a to pass through. In the present embodiment, a portion of the separator 27, the second engagement member 22 a, the second magnetic member 23, and the modified cover 25 form a protruding portion together corresponding to the groove 15.

FIG. 8 to FIG. 10 are schematic action views of the first engaging member of the adaptor module of the electronic device of FIG. 4 and the second engaging member of the functional module thereof. It should be mentioned that, in FIG. 8 to FIG. 10, to clearly show the action between the first engaging member 13 a of the adaptor module 10 a and the outer gear set 222 of the functional module 20 a, only a portion of the functional module 20 a is shown. Referring to FIG. 8 first, when the protruding portion of the functional module 20 a is extended into the groove 15 of the adaptor module 10 a, if the first engaging member 13 a is aligned with the teeth 223 of the outer gear set 222, then the user only needs to slightly rotate the functional module 20 a to the state of FIG. 9 such that the first engaging member 13 a corresponds to the engaging groove 221 of the outer gear set 222. In the present embodiment, since the magnetic force of the second magnetic member 23 of the functional module 20 a is greater than the magnetic force of the first magnetic member 14 of the adaptor module 10 a, the magnetic first engaging member 13 a is attracted by the second magnetic member 23 of the functional module 20 a and is moved out of the chute 16 (i.e., inside the groove 15 as shown in FIG. 5). As a result, the first engaging member 13 a is extended into the engaging groove 221 of the outer gear set 222 as shown in FIG. 10 to complete the engagement.

In the present embodiment, the adjacent two teeth 223 of the outer gear set 222 have two opposite inclined walls 224 therebetween, and when the functional module 20 a is to be removed, the first engaging member 13 a originally located in the engaging groove 221 is pushed by one of the inclined walls 224 and exits the engaging groove 221 simply by slightly rotating the functional module 20 a. After the functional module 20 a is separated from the adaptor module 10 a, the first engaging member 13 a is attracted by the first magnetic member 14 again and retracted in the chute 16. Of course, in other embodiments, the restoring member can also be replaced by an elastic member (such as a spring) connected to the first engaging member 13 a, provided the pull from the elastic member to the first engaging member 13 a is less than the magnetic force from the second magnetic member 23 to the first engaging member 13 a.

In summary, the electronic device of the invention can be assembled to a regular lamp holder via a lamp connector design of the adaptor module, and the user can dispose the electronic device of the invention on a desired lamp holder themselves without requiring an additional procedure to provide a relevant circuit and mounting bracket. Therefore, the electronic device of the invention is rather convenient to install. Moreover, in an embodiment, the electronic device can further include a functional module. Since the functional module can be engaged to the adaptor module in a detachable manner and can be electrically connected to the lamp holder via the adaptor module, the user can select the desired type of functional module to be assembled to the adaptor module themselves or switch the functional module as needed to meet the diverse needs of the user. Moreover, the functional module and the adaptor module are fixed via an engagement method, such that installation and removal are more convenient and the function of rapid installation and removal is achieved.
